KNIFE-CARRYING MECHANISM FORSOLE-CUTTING MACHINES.

1'0 all whom it may concern/.-

Be it known that I, ALLIsON MORRIs STIOKNEY, of Medford, in the countyof Middlesex and State'of Massachusetts, have in vented a new and usefulImprovement in Knife-Carrying Mechanism for Sole-Cutting Machmes, ofwhich the following is a specifihad to the accompa cation, referencebeing nyinggdrawings, making a. part hereof, in Figure 1 is.a frontview. Fig. 2 is a side View, and Fig. 3 is'a section on line 3 3 ofFigs. 1 and 2.

- y invention is an improvement on the knife-carrying mechanism shown inmy Patent No. 647,888, dated April 17, 1900;

consists in connecting the blade-holder with that patent by means of twolinks which are so arranged relatively that they always I of the bladecarried =byithe blade-holder in proper relation to the edge of theexternal form against which theblade is carried by the knife-carryingmechanism, the parallel links, being so disposed that the blade iscaused to about which the blade is carried by the knifecarrier. 1 V k cIn the drawings the knife-carrier made up of the mairicarrier A, ma' thespindle B at its lower end and roper is e fast-to SpecificationofLetters Patent.

and it maintain thec'utting ed e accurately follow the external form.

with the links D D, pivoted at d d at one end links D D to theblade-holder A, which is shaped to receive the pivots d 01 which connectthe links D D to the blade-holder A.

The blade (1 is secured in the blade-holder A, as shown in my patentabove referred to, and is otherwise as fully described in that patent,except that the motionsgiven to it are adapted much more perfectly tothe variations of the edge of the form F than is possible with theknife-carrying mechanism described in that patent... I What I claim asmy invention is- 1. In a knife-carrying mechanism for solecuttingmachines the combination of a knifecarrier; a blade holder; and parallellinks connecting the knife-carrier and blade-holder to guide the bladein its movements with relation' to the carrier.

2. In a knife-carrying mechanism for solecutting machines thecombination of a knifecarrier'; a blade holder; and 'arallel linksconnecting the knife-carrier an blade-holder to guide and support theblade in its movement with relation to the carrier.
